Scattering and phase shifts
Scattering and phase shifts play a central role in many fields of physics and are especially relevant for electronic structure in the properties of pseudopotentials (Ch. 11) and the formulation of augmented and multiple-scattering KKR methods (Chs. 16 and 17). The purpose of this appendix is to collect the formulas together and to make added connections to scattering cross sections and electrical resistivity.
J.1 Scattering and phase shifts for spherical potentials
Scattering plays an essential role in interesting physical properties of electronic systems and in basic electronic structure theory. Scattering due to defects leads to such basic phenomena as resistivity in metals and is the basis ...
